From the negligible content of oligosaccharides in fruit and marked decrease in percentage of oligosaccharide- ^<14>C in petiole and fruit tissues, oligosaccharides as major translocates in cucumber and melon plants seemed to be metabolized to sucrose or further to hexoses in petiole and peduncle. However, it was apparent that some ^<14>C was transported as oligosaccharides into fruit without breakdown.

从果实中低聚糖的含量可以忽略不计以及叶柄和果实组织中低聚糖- ^ C的百分比显著降低来看<14>，低聚糖在黄瓜和甜瓜植株中的主要转运体似乎是在叶柄和果梗中被代谢为蔗糖或进一步被代谢为己糖。然而，很明显，一些^<14>C以低聚糖的形式运输到果实中而没有分解。
